Graphing Glow-in-the-Dark Paint Scenario
Isaac wants to paint the ceiling of his room with a glow-in-the-dark galaxy design since
his bedroom is in the basement and has no windows. He wants the glowing effect to last
through the whole night, but he doesn't know which type of paint will glow the longest.
So, he has decided to create an experiment in order to choose the best paint for his room.
Isaac found 7 available brands of glow-in-the-dark paint at the local store. Using these
samples, he painted each paint on a different square of poster paper that were each
measured to be 1 foot x 1 foot. He placed them all in his dark room, and set up a video
camera to record how long each sample of paint glowed. He recorded the time that each
paint sample stopped glowing.
